Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Contribute to translation
13 avril 2011You can help us to improve the language used in the software interface to make MediaSPIP more accessible and user-friendly. You can also translate the interface into any language that allows it to spread to new linguistic communities.
To do this, we use the translation interface of SPIP where the all the language modules of MediaSPIP are available. Just subscribe to the mailing list and request further informantion on translation.

How to get your Piwik plugin translated in many languages ?
About a year ago we introduced the Piwik Marketplace to make it easy for developers to share their plugins with all Piwik users.
As Piwik is currently available in 54 languages we would love to have as many plugins as possible available in at least a few of those languages.
Currently most plugins on the Marketplace are only available in English and sometimes some other languages. To improve this situation, we offer plugin developers the possibility to use the power of our translators community to get their plugins translated.
Some plugin developers are already using this service and some very popular plugins like BotTracker or CustomOptOut have already been translated in more than 10 languages !
Getting translations for your plugin
As long as you are developing an open source plugin hosted on Github, you may get in touch with us (translations@piwik.org) in order to get your plugin translated by the Piwik translators community.
You will need an account on Transifex.com. If you use Transifex with a social login, please ensure to set a password in your account settings. This will be required for fetching new translations into your plugin repository.
Importing your plugin’s strings in the translation platform
While doing the initial setup for your plugin, we will import your english translation file (
en.json) in your Github plugin repository and we will configure an auto-update for this file. Source strings on Transifex will automatically synchronise with your plugin repository. When you change any string in youren.jsontranslation file, the updated English strings will automatically be imported in Transifex.How to fetch your plugins translations into your repository
As soon as we have set up your plugin within our project Piwik on Transifex and there are new translations available, you will be able to update your plugin translations using the Piwik console. You will need a locally installed Piwik with development mode enabled, and your plugin installed. To update the translations go to the Piwik directory on your development box and execute the following command :
./console translations:update -u {YourTransifexUserName} -p {YourTransifexPassword} -P {YourPluginName}We are looking forward to seeing your Piwik plugins available in more languages ! For more information, check out our Translations plugin developer guide.
Happy hacking,

How can I fix a segmentation fault in a C program ? [duplicate]
31 mars 2023, par ipegasus

Possible Duplicate :

Segmentation fault



Currently I am upgrading an open source program used for HTTP streaming. It needs to support the latest FFmpeg.
The code compiles fine without any warnings, although I am getting a segmentation fault error.


How can I fix the issue ? And / or, what is the best way to debug ? Please find attached a portion of the code due to size. I will try to add the project to GitHub :)


Sample Usage


# segmenter --i out.ts --l 10 --o stream.m3u8 --d segments --f stream


Makefile


FFLIBS=`pkg-config --libs libavformat libavcodec libavutil`
FFFLAGS=`pkg-config --cflags libavformat libavcodec libavutil`

all:
 gcc -Wall -g segmenter.c -o segmenter ${FFFLAGS} ${FFLIBS}


segmenter.c
